Crush Injury from Gearbox
Date of Incident: 21 August 2014
Description:
During a major component change, a 14.5tn gearbox became snagged and moved uncontrolled which lead to substantial bruising to the lift supervisor/dogman's arm.
As the gearbox was slewing left, it was noticed that the gearbox wasn't moving and was possibly snagged. A "stop, stop" was called by the dogman, but the operator didn't hear and continued to slew. Not knowing the crane was still slewing slowly left, the dogman then instructed the team to look for a snag point. As he put his arm on the rotating shaft to look for a snag underneath the gearbox, it then moved side wards and hit the couplings. This caused the gearbox to stop on one side and pivot towards the generator with the technicians arm caught between them. The gearbox stopped and swung back, allowing the technician to get his arm free. At this stage, the crane operator felt a shudder and stopped all crane movements.
